Application filed August 2, 1909. Serial No. 510,829.

. To all whom it concerm,

Be it known that I, EDWIN I. SPENCER, a citizen of the United States, residing at \Vichita. in the county of Sedgwick and State ofKansas, have invented a new and useful Jack for Automobiles, of which the following is a specification.

This invention relates to improvements in jacks for vehicles and has especial reference to a device adapted to lift the wheels of automobiles from ditches and ruts in places where is'is inconvenient to obtain a footing forthe jack beneath the axle.

The invention consists in an adjustable frame which is adapted to pass over the end of the axle and rest upon the ground at opposite sides of the same and in which is mounted a lifting screw carrying means for engaging the end of the axle so that uponrotation of the screw the axle will be lifted and the wheel removed from the ditch or rut into which it has fallen. Such a device, is illustrated in the accompanying drawings and the invention consists in. certain novel features of the same as will be hereinafter first fully described and then pointed out in the ap ended claim.

In the drawings igure 1 is an elevation of in improved jack in its operative position; ig. 2 is a similar view showing the device folded; Fig. 3 is a detail perspective view of the hanger or strap for engaging the hub or end of the axle; and Fig. 4 is a detail horizontal section; Fig. 5 is a detail view of a hook which may be em loyed to lift the wheel by engaging the spo es of .the same.

In carrying out my invention I employ a head 1,'to the opposite ends of which are pivoted the legs 2 which are constructed of two members, preferabl of channel iron, adapted to telescope an having the lower members provided with broad feet 3 adapted to rest upon the ground, as clearly shown in Fig. 1. In the preferred form of the invention, which is illustrated in the drawings, the lower member of the legs 2 fits over the upper member and carries a set screw 4 which is adapted to bind against the side of the upper member and thereby secure the two members in their adjusted ositions. In order to prevent collapse of t e device while in use, a brace 5 is pivoted at one end to one of the supportin legs and projects therefrom to pass throng a keeper 6 on the side of the other leg and is secured at the proper dpoint by means of a set screw 7 mounte 111 the said kee er and binding against the brace, as will, e readily understood. The lifting screw 8 is threaded within the head 1 and is rovided at its'upper end with the usual soc eted head 9 ada ted to be engaged by a lever or turning ro 10 so that rotary movement may be imparted to the screw and the screw thereby caused to travel up or down withinthe head 1 of-the support. At the lower end of the screw, I provide a double hook 11 which is swiveled on this screw and is adapted to be engaged by the hanger or stra 12 which is passed around the axle or on of the hub and has its ends provided with transverse openings 13 adapted to be engaged over the hooks 11 so that when the screw 8 is moved upward the said strap or han er'will becaused to draw upon the axle or ub of the automobile and thereby lift the same, as will be readily understood. Should the projecting end of the hub not be long enough to .permit the use of the strap 12, the hooks 14 are hun on the double hook 11 and engaged under the spokes of the wheel so that u on rotation of the screw a lifting force wil be applied to the wheel.

In using the ordinary lifting jacks or jack screws to remove automobile wheels from deep rats or ditches, it is necessary to dig around the wheel so as to form a hole or opening in the ground in which the jack may be placed beneath the axle. This work necessarily consumes considerable time and is very laborious. In using my device the supporting frame is simp y opened and placed upon the round ad acent the side of the wheel with t eend of the hub or axle projecting between the supporting legs and below the end of the screw. The hanger or strap is then passed beneath theaxle or hub and its ends engaged over the hooks 11 and the operating lever 10 then swung horizontally so as to rotate the screw, whereupon the screw will ride upward through the head 1 and will draw the wheel from the ditch.

The device is extremely simple in its construction, can be readily set up for use or put aside for storage or transportation and efficiently performs the desired work.

Having thus described my invention, what I claim is A jack adapted to ass over the end of an axle close to the w eel thereof consisting of a head, a telescoping supporting member pivoted to and depending from each end of the head, the said members being provided with ri id feet at their lower ends pro'ectin latera 1y beyond the sides of the sai mem ers, a brace ivoted to one of said members and adjustab y secured to the other member, a lifting screw threaded in the head and extending through the same, a hook swiveled on the lower end of said screw, and

gheisl engaging means suspended on said 10 In testimony that I claim the foregoing as m own, I have hereto aflixed my signature in the presence of two witnesses.
